DescriptionThis is a premium, ultra-fast, and robust professional telephoto lens. Its lightweight construction incorporates a magnesium die-cast barrel, and professional-grade dust and moisture sealing allows it to be used in more rugged situations. This lens features the improved Vibration Reduction (VR II) system that allows handheld telephoto shooting, even in less-than-ideally lit conditions. The VR system minimizes image blur caused by camera shake, and offers the equivalent of shooting at a shutter speed of about 4 stops faster. In addition, this lens also features the Tripod Detection mode, which reduces vibration that may occur due to shutter release, when mounted on a tripod. The Silent Wave Motor (SWM) feature provides swift auto-focus with superior accuracy and ultra-quiet operation. This G-type lens does not feature an aperture ring on the lens body, resulting in a lighter and more compact lens.
